Abstract :
The design of nonlinear-phase FIR digital filters is considered and it is shown that the design problem can be formulated as a semidefinite programming (SDP) problem. Specifically, we consider an equiripple design in which the phase response in the stopbands and transition bands are not required to be linear, and a design which approximates the desired frequency response in passband in equiripple sense and the desired frequency response in stopband in least-squares sense
